Andrew Gardner sent Shopper's Drug Mart an email complaining that he was receiving mail from the company for someone named Matthew.

Gardner wrote the store a mildly humorous message pondering why he was receiving Matthew's mail:

Naturally, I can draw one of two conclusions from this: 1) that Matthew is a previous resident of this address …Or 2), and I may be going out on a limb here, Matthew is a future resident of this address, and seemingly against the laws of causation, your computer system has this information and prematurely mailed an advertisement to him before he’s actually lived here.

Gardner was shocked when he received this response from the company eluding to a post-apocalyptic future:

Thank you for writing us. We apologize if you have been receiving mail from Shoppers Drug Mart that was addressed to another customer. Unfortunately, we cannot comment on any research projects that we may currently be conducting. However, we would appreciate it if you could provide us with some additional information that would help us determine when the mailer you received was sent. Could you please let us know if it contained any of the following advertisements?1) Now at Shoppers Drug Mart: EverexisCure any disease instantly with Everexis!
